PETER R. ALPHONSO, OF WEWOKA, OKLAHOKA, ASSIGNOR TO THE ,ARGENT CORPORA-TION, OF SHREVEPORT, LOUISIANA, A.CORPORA TIQN LOUISIANA BOILER sxnumiaApplication filed February 7,1931. Serial No. 514,298.

The invention relates to boiler skimmers, and has for its object toprovide a device of this character comprising a float supported pipehaving branch pipes within the boiler, and provided with slots orapertures through which the scum on the water is forced by steampressure within the boiler through a discharge pipe.

A further oo ect is to provide a flexible connection between thedischarge pipe and the float supported pipe, whereby said floatsupported pipe and its branch pipes, will rise and fall with the waterlevel within the boiler where it will be in operative position at alltimes.

A further obJect is to provide the ends of the float supported pipe withtransverse members, to the ends of which the floats are connected atopposite sides of the pipe for maintaining the pipe and the branch pipesin horizontal position. at all times.

A further object is to provide the discharge pe with a valve remotelycontrolled, whereby the operator may allow the steam within the boilerto force the scum through the float supported pipes, the flexible pipeand through the discharge pipe, which may lead to any suitable source ofdischarge.

With the above and other objects in view the invention resides in thecombination and arrangement or parts as hereinafter set forth, shown inthe drawing, described and claimed, it being understood that changes invthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawing Figure 1 is a perspective View of a conventional form ofboiler, showing the skimmer applied thereto.

Figure 2 is a horizontal sectional View through portions of the skimmer.

Figure 3 is a vertical transverse sectional view through the skimmer,the flexible discharge pipe and the control valve.

Referring to the drawing, the numeral 1 designates a conventional formof boiler, and disposed within the boiler is an elongated boiler skimmer2. The boiler skimmer 2 is formed from a plurality of pipe sections 3connected together by pipe crosses 4, and by a T 5, to which isconnected the upwardly extending flexible pipe 6. Threaded'on the endpipe sections 3 are T fittings 7, in the tranverse portions of which arethreaded the studs 8 of the floats 9. that the floats 9 are disposed onopposite sides ofthe central conduit, therefore the transverse branchpipes 10, which are threaded into the crosses 4 will be maintained in ahorizontal position at all times, as the water level 11 within theboiler rises and falls, therefore it will-be seen a particular waterlevel will not have to be maintained within the: boiler. The flexibledischarge pipe 6 has sufficient slack therein to allow a wide range ofupward and downward movement ed avalve 14, and connected to the valve cas-- ing 3 is a discharge pipe 15, which may lead to any'suitable sourceofdischarge, which would naturally vary with different installations.Valve 14 is provided with a valve stem 16, angularly shaped, to which isconnected an operating rod 17, and by means of which an operator mayopen or close the valve as desired.

When it is desired to clean the boiler-of scum whichgathers on thewater, the operator, through manipulating the rod 17, rotates the valve14 to openposition as shown in figure 3; then the steam pressure withinthe boiler will rush through the slots 18 in the branch. pipes 10, andwill suck and force scum adjacent the openings through the branch pipes,the various fittings forming the skimmer and through the flexible pipe6, valve 14 and discharge pipe 15. It will be obvious, as the waterwithin the boiler is constantly circulating in the usual manner, theskimmer will move transversely and longitudinally within the boiler,thereby assuming different positions, and insuring the skimming of theentire surface of the water.

It will be noted This movement is permitted by the slack in the flexiblepipe 6.

From the above it will be seen that a boiler skimmer is provided forremoving the scum from the surface of the water, so it will not be takenup in the steam and carried tovarious pieces of machinery andinterfering with the operation of the machinery It will also be seenthat the device is simple in construction and operation, and can beeasily and quickly applied to conventional boilers without varying theconstruction thereof, which is a desirable feature,

which allows the device to be easily applied to boilers now in use.

The invention having been set forth What is'claimed as new and usefulis 1. The combination with a boiler, a skimmer disposed within saidboiler, said skimmer being, float supported, a slack flexible dischargepipe connected to the boiler above the skimmer, said skimmer beingformed froma plurality of apertured pipes, said flexible pipe connectionbetween the ski-mmer and the boiler forming means whereby said skimmermay move laterally in all directions. 7

2. The combination with a boiler, of: a skimmer disposed in said boiler,sa-id skimmer'c'omprising a plurality of connected apertured pipes,floats carried by said skimmer and forming means for maintaining saidskimmer in a horizontal position, a discharge pipe carried by the boilerabove the skimmer, and an upwardly extending slack flexib'le pipeconnecting the skimmer and discharge pipe and through which scum'on thesurface of water within the boiler is forced, said flexible pipe havingsufficient slack therein to allow lateral movement of the skimmer in alldirections.

In testimony whereof he hereunto aflixes his slgnature.

PETER A LPHONSO.
